Colourising would make no difference to the scripts, direction or performances so what does it actually give us.

Surely the only reason to have them in colour is to get extra sales among people who won't watch B&W and lets face it if they can't cope with B&W the pacing and style of the 60's episodes will be just as problematic!

This is what I was trying to say.

And as far as TOS goes, I'll be the first one to acknowledge its weaknesses. I definitely don't watch it for the special effects. At this point, it's more of a nostalgia thing.
